First Solar Ha Images
« on: July 31, 2011, 09:47:31 PM »
Taken on the 23rd July and tweaked in Photoshop CS2.  A whole new learning curve with Solar imaging.

Still, at least I got something.

Thanks Guys, I was quite pleased with the result.  I have learned two things though,  90% of the data is in the red channel, and you need to have a 2 stops difference (at least) between the solar surface (for granulation) and the prominences (which are dimmer).  So to do this properly one needs two sets of exposures and then put them together - so my photoshop skills need to improve.  The only way I got the images above was by playing around a lot with photoshop on the single image.
 
Yes David, the Coronado II 60 BF10 seems to work okay, although it is not without its idiosyncracies.  I can get focus using a variety of EPs, but with the DSLR I need to put a x2 or x3 barlow in place.  Still, using the x2 barlow gives a reasonable image size, so I am not complaining.  But the Solarmax uses a clamshell and not rings, and I am having a difficulty finding a dovetail and screws to fit to this, so at the moment it sits on the Skytee using a simple phototripod thread (not as secure as I would like).  I need to have the scope properly mounted on a dovetail to fit it to the HEQ5 and be able to stack lots of images.  I will find a way.
 
See you at the next meet.
 
Tom

Very nice Tom - Yep, you now need to start learning Photoshop.... Layers is what you want.  Crackers though, would love a solar scope but just dont have the money available.
